Can someone share a working configuration (gpu and mem clock/v and config) for v8 for rx580 8Gb/4Gb?
On v6-v7 I have made a configurations but with v8 I'm unable to get one that stay stable!!! 
Actualy I'm on 1150gpu/2000mem/850mv and

{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : X, "multi_hash":1696 }    for 8Gb (doublethread)
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "index" : X, "multi_hash":944 }      for 4Gb (doublethread)

Whit this configuration I can get 950h/s on 0.33b4

I also did some test for bittube but also here I don't reached a stable configuration!
The system sometimes crash during the job (the card that goes into error changes almost every time) other times the miner start and stop immediately after connection with the pool (for this problem I think a problem with a card but it don't write which card goes wrong).

For all this problem I create this scheduled task procedure (win10): if something goes wrong the system restart itself (on startup I have the bat that start a miner process, usually or your or phoenixminer)
